Reducing Emergency Department Utilization for Pediatric Behavioral Health Crises Through High-Intensity Outpatient Behavioral Intervention

128 Background: Emergency department (ED) utilization for non-emergent medical problems is an inefficient use of medical resources. During calendar year 2013, 224 RIH adult cancer patients presented to the RIH ED. Retrospective review indicated up to 50% of these ED visits were avoidable. Methods: This project was developed for the ASCO Quality Training Program. A multidisciplinary team was assembled to address ED utilization. Retrospective chart review of ED visits included time and reason for visit and primary tumor site. The team selected the Lung Cancer as the target group, developed a cause-and-effect analysis for ED visits, administered a patient survey, and implemented a series of Plan-Do-Study-Act (PDSA) cycles. The team implemented a patient education process of nurse sick-line symptom management and same-day sick visits at RIH CCC as well as developing a single-page patient “sick-line tool” with oncology nurse sick-line contact telephone numbers. A patient navigator introduced the sick-line tool at the first visit and its usage was reinforced at subsequent visits. Results: For RIH CCC lung cancer patients, a standardized symptom-control education process correlated with 30% decrease in ED visits for any presenting complaint (42 visits vs. 60 visits) and 32% decrease in ED visits with presenting complaint of pain (13 visits vs. 19 visits) during January/February 2014 compared to January/February 2013. We did not find significant differences between the proportion of ED visits during Cancer Center business hours, evenings, or weekends. Sick-line calls were found to increase by 53% during January 2014 compared to December 2013 with an additional 35% increase in February 2014. Conclusions: A standardized patient education process resulted in a significant decrease in ED visits, concurrent with an increase in outpatient sick-line utilization. This may reflect an improvement in efficiency of outpatient cancer patient care in a single-institution setting. Given other reports of increased ED utilization by lung cancer patients for similar presenting reasons, these improvements may be generalizable to other institutions.

Rising utilization of US emergency departments: Maybe it is time to stop blaming the patients

Patient Navigation to Reduce Emergency Department (ED) Utilization Among Medicaid Insured, Frequent ED Users: A Randomized Controlled Trial

Emergency department (ED) utilization is a major driver of health care costs. Specialist physicians have an important role in addressing ED utilization, especially at highly specialized, academic medical centers. We sought to investigate whether reporting of ED utilization to specialist physicians can decrease ED visits. This study analyzed an intervention to reduce ED utilization among ED patients who were followed by pediatric gastroenterologists. In May 2013, each pediatric gastroenterologist began receiving reports with rates of ED use by their patients. The reports generated discussion that resulted in a cultural and process change in which patients with urgent gastrointestinal (GI)-related complaints were preferentially seen in the office. Using control charts, we examined GI-related and all-diagnoses ED use over a 2-year period. The rate of GI-related ED visits decreased by 60% after the intervention, from 4.89 to 1.95 per 1000 office visits (P < .001). Similarly, rates of GI-related ED visits during office hours decreased by 59% from 2.19 to 0.89 per 1000 (P < .001). Rates of all-diagnoses ED visits did not change. Physician-level reporting of ED utilization to pediatric gastroenterologists was associated with physician engagement and a cultural and process change to preferentially treat patients with urgent issues in the office.

Young adults with sickle-cell disease have increased emergency department (ED) utilization and increased risk of mortality for unclear reasons. Emergency Department Reliance (EDR) differentiates excessive ED use due to increased need in chronic illness from increased use due to limited access to outpatient care. A higher EDR has been used to define excessive reliance on the ED and thus access to care issues leading to increased ED utilization. We conducted a retrospective cohort study of sickle-cell disease patients within the Wisconsin Medicaid database over a 5-year period to examine EDR during the transition period from childhood to adulthood. The study population included four distinct groups: (1) children, (2) patients transitioning from pediatric to adult providers, (3) young adults, and (4) adults age 31-45. Rates of visits per year were calculated for ED visits and outpatient visits for all diagnoses and sickle-cell disease-related diagnoses. Overall, we found increased EDR among the transition group and young adults compared to children and adults for sickle-cell disease-related diagnoses. These findings suggest access to care issues play a significant role in the increased ED utilization seen during the transition period from pediatric to adult providers in sickle-cell disease.

Emergency department (ED) utilization is a major driver of cost. Specialist physicians have an important role in addressing ED utilization, especially at tertiary medical centers that treat highly specialized patients. We analyzed if reporting of ED utilization to pediatric specialist physicians can decrease ED visits. Physicians within pediatric neurology, hematology and oncology, infectious diseases, and pulmonary divisions received their ED use reports. By using control charts, we examined if this intervention decreased the rate of ED utilization. Overall, for the 4 divisions, specialty-related ED utilization decreased significantly during all hours, weekdays, and office hours. This was in the setting of ED utilization increasing for all diagnoses ED visits. Pediatric ED volume did not change during the study period. Physician-level reporting of ED utilization was associated with a reduction in ED use by patients managed by our pediatric specialists.

Although 72-hour emergency department (ED) revisits are increasingly used as a hospital metric, there is no known empirical basis for this 72-hour threshold. The objective of this study was to determine the timing of ED revisits for adult patients within 30 days of ED discharge. This was a retrospective cohort study of all nonfederal ED discharges in Florida and Nebraska from April 1, 2010, to March 31, 2011, using data from the Agency for Healthcare Research and Quality (AHRQ) Healthcare Cost and Utilization Project (HCUP). ED discharges were followed forward to identify ED revisits occurring at any hospital within the same state within 30 days. The cumulative hazard of an ED revisit was plotted. Parametric and nonparametric modeling was performed to characterize the rate of ED revisits. There were 4,782,045 ED discharges, with 7.5% (95% confidence interval [CI] = 7.4% to 7.5%) associated with 3-day revisits, and 22.4% (95% CI = 22.3% to 22.4%) associated with 30-day revisits, inclusive of the 3-day revisits. A double-exponential model fit the data best (p < 0.0001), and a single hinge point at 9 days (multivariate adaptive regression splines [MARS] model) yielded the best linear fit to the data, suggesting 9 days as the most reasonable cutoff for identification of acute ED revisits. Multiple stratified and subgroup analyses produced similar results. Future work should focus on identifying primary reasons for potentially avoidable return ED visits instead of on the revisit occurrence itself, thus more directly measuring potential lapses in delivery of high-quality care. Almost one-quarter of ED discharges are linked to 30-day ED revisits, and the current 72-hour ED metric misses close to 70% of these patients. Our findings support 9 days as a more inclusive cutoff for studies of ED revisits.

Patterns of Emergency Department Utilization of Adolescents and Young Adults Living with Sickle Cell in North Carolina

Sickle cell disease (SCD) is a complex hemoglobinopathy. Vaso-occlusive episodes are the primary cause of emergency department (ED) utilization among individuals with SCD. Literature lacks a standardized definition for high ED utilization. To explore ED utilization, redefine high ED utilization, and describe factors associated with super-high ED utilization among individuals with SCD. This retrospective cohort study analyzed the North Carolina Hospital Discharge Datasets (2013-2019). Participants were included if they had SCD, defined as at least 3 SCD visits (ED, inpatient, or outpatient surgery) in a rolling 5-year period. All age groups, sexes, and payers, regardless of state of residence, were included. Data were analyzed from July 2023 to August 2024. Variables included sex, race, ethnicity, age, age at death, distance (in miles) to the closest SCD center, number of annual ED visits, and social vulnerability index (SVI). To determine ED utilization categories, first the distribution of people based on the number of annual ED visits was examined, then the categories across years were identified to determine the data-informed cutoff for each category. Univariate analysis determined differences between participants based on the ED utilization category using χ2 tests of independence or analysis of variance, as applicable. Descriptive statistics were conducted to describe characteristics of utilization in the sample and by ED utilization group. A parsimonious multinomial regression was conducted using significant factors from the univariate analysis. The cohort included 9964 unique patients (5364 [53.83%] female; mean [SD] age, 24.49 [17.54] years), including 9355 Black patients (93.89%), with 100 188 total ED visits from 2013 to 2019. ED visits were categorized into 4 levels: low (0-1 visits per year), moderate (2-9 visits per year), high (10-32 visits per year), and super high (≥33 visits per year). A small subset (178 patients [1.79%]) exhibited super-high ED utilization, contributing disproportionately to the total number of ED visits. Older age, younger age for in-facility deaths, and higher SVI were significantly associated with higher ED utilization. Patients with high utilization were more likely to die, die younger (eg, median [IQR] age at death, 33.0 [30.0-44.0] years in the super-high utilization group vs 50 [38.0-61.0] years in the moderate utilization group), use multiple EDs (eg, 93.8% of participants in the super-high utilization group vs 40.08% of participants in the moderate utilization group), and reside in counties more disadvantaged on socioeconomic and transportation characteristics. This cohort study of 7 years of North Carolina Hospital Discharge Data described 4 new categories of ED utilization in SCD. These categories could be used to reframe how high ED use is determined.

Increased Use of the Emergency Department After Health Care Reform in Massachusetts

The authors sought to describe the epidemiology of and risk factors for recurrent and high-frequency use of the emergency department (ED) by children. This was a retrospective cohort study using a database of children aged 0 to 17 years, inclusive, presenting to 22 EDs of the Pediatric Emergency Care Applied Research Network (PECARN) during 2007, with 12-month follow-up after each index visit. ED diagnoses for each visit were categorized as trauma, acute medical, or chronic medical conditions. Recurrent visits were defined as any repeat visit; high-frequency use was defined as four or more recurrent visits. Generalized estimating equations (GEEs) were used to measure the strength of associations between patient and visit characteristics and recurrent ED use. A total of 695,188 unique children had at least one ED visit each in 2007, with 455,588 recurrent ED visits in the 12 months following the index visits. Sixty-four percent of patients had no recurrent visits, 20% had one, 8% had two, 4% had three, and 4% had four or more recurrent visits. Acute medical diagnoses accounted for most visits regardless of the number of recurrent visits. As the number of recurrent visits per patient rose, chronic diseases were increasingly represented, with asthma being the most common ED diagnosis. Trauma-related diagnoses were more common among patients without recurrent visits than among those with high-frequency recurrent visits (28% vs. 9%; p<0.001). High-frequency recurrent visits were more often within the highest severity score classifications. In multivariable analysis, recurrent visits were associated with younger age, black or Hispanic race or ethnicity, and public health insurance. Risk factors for recurrent ED use by children include age, race and ethnicity, and insurance status. Although asthma plays an important role in recurrent ED use, acute illnesses account for the majority of recurrent ED visits.

22 Background: ED utilization among patients with cancer is often cited as a potential metric to improve the quality of oncology care. However, efforts to understand emergency department (ED) utilization among patients with cancer receiving IV chemotherapy are lacking. We sought to describe sociodemographic and clinical factors associated with ED utilization and explore predictors of ED arrival time. Methods: We conducted a quality improvement assessment of patients who visited the ED within 30-days of receiving IV chemotherapy at Massachusetts General Hospital from October 2017 to January 2018. We used descriptive statistics to describe the sociodemographic and clinical factors associated with ED visits. We used multivariable regression models to explore predictors of the following outcomes: (1) ED visit occurring during normal clinic hours; and (2) ED visit occurring during the weekend. Results: Of the approximately 2,600 patients receiving IV chemotherapy during the assessment period, we identified 500 ED visits (~19.2%). For these ED visits, median patient age was 65 years (range: 22-93), and 49.6% were female. The majority were white race (84.8%), married (63.6%), diagnosed with metastatic disease (70.4%), and 8+ days since receiving most recent chemotherapy (71.4%). The most common cancer types were gastrointestinal (24.2%), lung (13.2%), and lymphomas (11.0%). The most common reason for ED visits included pain (20.4%), fever/cold symptoms (18.0%), and fatigue (11.0%). Over half (50.4%) of ED visits occurred during normal clinic hours and over one-fourth (28.2%) occurred during the weekend. We found that ED visits were less likely to occur during normal clinic hours for patients with lymphomas (OR = 0.44, P = 0.013) compared with other cancer types. ED visits were less likely to occur during the weekend for patients of older age (OR = 0.98, P = 0.020). Conclusions: We identified a substantial number of ED visits among patients with cancer within 30-days of receiving IV chemotherapy, often occurring during normal clinic hours and most commonly for pain, fever/cold symptoms, and fatigue. These findings highlight issues to address when seeking to reduce ED utilization and enhance cancer care quality.

The aim of this study was to investigate the hypothesis that a significant percentage of urgent care center to pediatric ED transfers can be discharged home without emergency department (ED) resource utilization. A retrospective chart review was completed for a 6-month period on all patients transferred from urgent care centers. A data collection tool focusing on demographics, diagnoses, reason for transfer, ED resource utilization, ED disposition, and 72-hour ED return was used. Each encounter was classified as "urgent" or "nonurgent" based on resource utilization criteria. Descriptive statistics were reported for demographics, encounter data, and 72-hour ED return stratified by nonurgent versus urgent classification. Two-sample t, χ, and Fisher exact tests were used to assess differences in characteristics between the nonurgent and urgent groups. One hundred nine patients met inclusion criteria. Of these, 93 (85%) were discharged from the ED. Twenty nine (27%) of the transferred patients were discharged without ED resource utilization. Seventy-two-hour return was noted for only 1 patient who was again discharged at the subsequent encounter. A large proportion of patients transferred from urgent care centers were directly discharged from the ED without any ED resource utilization. Eliminating or reducing such transfers has the potential to limit the amount of nonurgent ED visits, thus producing cost savings and better patient care.

Social determinants of health are conditions, factors, and environments that impact people's health. One such metric of people's health is emergency department utilization, but there is less research exploring how social determinants impact the emergency department use of people with intellectual and developmental disabilities (IDD). This exploratory study examined the relationship between people with IDD choosing where and with whom to live—a social determinant of health—and emergency department utilization. We analyzed secondary Personal Outcome Measures data, and emergency department data from 251 people with IDD. Our findings revealed people with IDD who chose where and with whom to live had a 74% decrease in emergency department visits, regardless of their impairment severity. Choice in housing may improve people with IDD's health outcomes.

Introduction: It is critical for planning, clinical care and resource optimization to understand patterns of emergency department (ED) utilization. Individuals who have experienced adverse childhood experiences (ACE) are known to have more unhealthy behaviors and worse health outcomes as adults and therefore may be more frequent ED users. Adverse childhood experiences include physical, sexual and emotional abuse or neglect, substance abuse in the family, witnessing violence, having a parent incarcerated or parents getting divorced or separated. To date there are few studies exploring the relationship between ACE and ED utilization. Methods: This a mixed qualitative and quantitative study. It includes analysis of data collected through a survey, a retrospective chart review and focus group discussions. The survey was administered to a convenience sample of adult patients (CTAS 2 -5) presenting to EDs in Kingston Ontario, and consisted of two validated tools that measured exposure to ACE and resiliency. Demographic data and ED utilization frequency for 12 months prior to the index visit were extracted from an electronic medical record for each patient completing the survey. A sample of participants with a high ACE burden (ACE score &gt; 4) were invited to participate in focus groups to explore their experiences of care in the ED. Demographic, ED utilization and health status data were summarized and statistically significant patterns between high ACE and lower ACE patients were determined using Chi2t or t-tests. Transcripts from the focus groups were thematically analyzed using NVivo software by 2 independent researchers. Results: 1693 surveys were collected, 301 (18%) were deemed to have a high ACE score, data analysis is ongoing. The primary outcome is the relationship between ACE and the frequency of ED utilization among adult patients presenting to EDs in Kingston, ON. Secondary outcomes include evaluating the role of resilience as a potential mitigating factor, describing the demographics of high ACE burden frequent ED visitors, and the experiences of care for individuals with high ACE burden in the ED. These outcomes will be utilized to inform hypotheses for future studies and potential interventions aimed at optimizing ED utilization and patient care experience. Conclusion: This study provides novel insight into the relationship between ACE burden and ED utilization while also describing the demographics and experiences of care for ED patients with a high ACE score. Data analysis is on-going.
